An industrial fuel cell has to supply a continuous 20. MW to a perfectly efficient inverter at 123.V. Assuming it uses a hydrogen gas/air/PEM system, what are the needed flows of H₂ and air to the cells in standard m³/s? See the following simplified schematic. Assume each fuel cell produces 1.23 V.
